Description

Technical Field

[0001] The utility model relates to the technical field of compensators, in particular to a vibration-damping non-metallic compensator for a marine exhaust pipe. Background Art

[0002] The compensator utilizes the effective expansion and contraction of its working body, the bellows, to absorb the dimensional changes of pipelines, ducts, containers, etc. caused by thermal expansion and contraction, or to compensate for the axial, lateral and angular displacement of pipelines, ducts, containers, etc.

[0003] After the installation of traditional compensators, the fixing pins need to be removed. During the removal process, the corresponding bolts need to be unscrewed one by one, which is very cumbersome. In addition, the size of the traditional compensator fixing pins cannot be adjusted. Due to the size relationship, the specified effect may not be achieved when the compensator is installed. Therefore, the utility model proposes a non-metallic compensator for vibration reduction of marine exhaust pipes. Utility Model Content

[0006] Preferably, the telescopic rod is movably inserted into the main rod body, and a spring is fixed to one end of the telescopic rod disposed inside the main rod body.

[0007] Preferably, a slide groove is provided on the surface of the main rod body, the slide groove is communicated with the inside of the main rod body, a slider is slidably connected to the slide groove, the slider is fixed on the telescopic rod, and a sliding ring is fixed to the other end of the slider away from the telescopic rod.

[0008] Preferably, a connecting block is fixed on the other side of the sliding ring away from the sliding groove, a threaded rod is movably inserted on the connecting block, the bottom end of the threaded rod is fixedly connected to an end plate, and the end plate is fixed on the main rod body.

[0009] Preferably, the threaded rod is arranged on a portion above the connecting block and is threadedly connected to a bolt.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are that, in the utility model, the supporting member adopts a telescopic structure, so that its length can be freely adjusted as needed, and at the same time, it is fixed between the mounting holes provided on the flange, and then the length of the main rod body and the telescopic rod are adjusted according to the size of the compensator body, thereby playing the role of supporting the compensator body during the installation process. When dismantling, it is only necessary to unscrew the bolts and slide the telescopic rod to retract the telescopic rod into the main rod body, and then remove the entire supporting member. This design makes the supporting member easy to disassemble and reusable, and is not limited by size. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0017] like Figure 1-3 As shown, the utility model provides a technical solution: a non-metallic compensator for vibration reduction of a marine exhaust pipe, comprising a flange 1 and a compensator body 3 between the flanges 1, the compensator body 3 is fixed between the flanges 1, a flange hole 2 is penetrated through the flange 1, and mounting holes 5 are opened on the sides of the flanges 1 close to each other, and a support member 4 is installed in the mounting hole 5;

[0018] The support member 4 includes a main rod body 41 and a telescopic rod 42. The telescopic rods 42 are grouped in pairs. The telescopic rods 42 are correspondingly arranged at both ends of the main rod body 41. The telescopic rods 42 are correspondingly movably inserted in the main rod body 41. A spring 48 is fixed to one end of the telescopic rod 42 arranged inside the main rod body 41. The telescopic rod 42 is telescopically arranged in the main rod body 41. The overall length of the main rod body 41 and the telescopic rod 42 can be freely adjusted, so that the device can be adjusted and used according to the size of the compensator body 3 without being affected by the size.

[0019] The surface of the main rod body 41 is provided with a slide groove 49, which is connected to the inside of the main rod body 41, and a slider 47 is slidably connected to the slide groove 49, and the slider 47 is fixed to the telescopic rod 42. A sliding ring 46 is fixed to the other end of the slider 47 away from the telescopic rod 42. The slider 47 is used to drive the telescopic rod 42 to move up and down, thereby adjusting the length of the telescopic rod 42 in the main rod body 41 and changing the overall length of the support member 4.

[0020] A connecting block 45 is fixed on the other side of the sliding ring 46 away from the sliding groove 49, and a threaded rod 44 is movably inserted on the connecting block 45. The bottom end of the threaded rod 44 is fixedly connected to an end plate 43, and the end plate 43 is fixed to the main rod body 41. The threaded rod 44 is used to ensure that the telescopic rod 42 of the support member 4 will not move after the adjustment is completed, thereby ensuring that the compensator body 3 will not be deformed when the compensator body 3 is installed. After the installation is completed, the bolts are unscrewed, and the overall length of the support member 4 can be reduced by contracting the telescopic rod 42, so that the support member 4 can be easily removed from the flange 1;

[0021] The threaded rod 44 is provided on a portion above the connection block 45 and is threadedly connected to a bolt.

[0022] Working principle:

[0023] like Figure 1 - Figure 3 As shown, first, the sliding ring 46 drives the slider 47 to move, and then the slider 47 drives the telescopic rod 42 to retract into the main rod body 41. When the overall length of the main rod body 41 and the telescopic rod 42 is less than the length between the flanges 1, the telescopic rod 42 is correspondingly inserted into the mounting hole 5 opened on the flange 1, and then the sliding ring 46 is loosened. The telescopic rod 42 begins to extend outward under the elastic force of the spring 48 set at one end of the telescopic rod 42, thereby expanding the compensator body 3. In this process, the connecting block 45 slides on the threaded rod 44. After the adjustment is completed, it is only necessary to screw the bolts on the threaded rod 44 to ensure that the connecting block 45 does not move in the opposite direction. When the overall installation of the device is completed, it is only necessary to unscrew the bolts so that the sliding rings 46 on the main rod body 41 are close to each other, and the telescopic rod 42 is retracted. The entire supporting member 4 can be removed. This design makes the disassembly and assembly of the device more convenient and not limited by size.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
